For SSD which is best? IDE or AHCI

Glad you got it working.

I enabled AHCI mode using this tutorial, thank you.

Did anyone notice an increase in used resources after this? If I remember well, while in IDE mode, CPU usage while idle was around 2-3% and RAM usage was around 9%. Now, when idle, CPU is up to 10-12% with constant fluctuations/spikes and RAM is around 12-14%. A certain lag is also apparent. Is this a normal result after enabling AHCI mode?

EDIT:
Just to check out whether this was a "placebo" impression, I reverted back to IDE mode via BIOS. The change was clear: IDE mode works far better than AHCI mode. Didn't make any read/write measurments yet but CPU & RAM resources are back to normal. No lags whatsoever and my setup is very snappy indeed. I think I'll pass AHCI mode...

did you make the necessary changes in the registry..??

Are you running it off the Intel ports or the Marvell ports?

Your manual will tell you which ports are which. But the ports are usually of a different color. If I am not mistaken you have Intel ports and 2 Marvell ports. I would expect your sata ports to be the same color except for 2 of them a different color. The 2 would be the marvell ports. By many accounts, Marvell does not play nice with SSDs. I don't know that for a fact as I have never tried running one on my Marvell ports. My best guess would be that you would get better results from the Intel ports. Run your SSD from port 0. Download As SSD and open it and select your SSD drive at the top. Post a screenshot of the window. You do not need to run the test.

Oh about the ports, there are 2 SATA3 ports on my M/B (colored in blue) and I did connect the SSD & the HDD to them. Both disks are SATA3 capable. All other ports on the M/B only support SATA2 mode so I didn't bother connecting my disks to any of them.

Here is the drivers download section for my M/B (Win7 Pro, x64): http://www.gigabyte.us/products/prod...px?pid=3449#dl
I believe that the Marvell RAID Utility (SATA3) is the driver in question here (which I've already installed).

Your sata 3 ports are the Marvell ports. Try connecting to Intel port 0.
